The early civilization of the Incas is attributed to the ancient engineering of structures and especially the famous Inca road system. What can modern day engineering project learn from the inca roads system?
Thank you for the opportunity to help you with your question!
Inca road links several communities of different countries such as Argentina, Bolivia, Chile, Colombia, Ecuador and Peru.
Many modern roads have been destroyed with water while the Inca road that was built a long time ago still survives. Therefore, what a modern engine can learn from the Inca road is how to a construct roads that can be able to withstand the effects brought about by rains.
The modern engineers should pay attention to local conditions, e.g., On steep terrain they should build steps to dissipate the water's energy and counter erosion. At high altitudes, they should pave the way with local stone to protect the surface from ice and snowmelt. The walls of the roads should have holes to drain water.
